The Role of X and CT Image Measurement in Hip Arthroplasty in Patients with Parkinson's Disease

Objective: The study aims at evaluating if X-ray and spiral CT imaging is efficient in patients with Parkinson's disease after total hip arthroplasty (THA). Method: 76 patients with Parkinson combined with hip disease were selected as the study subjects, and grouped into the control group and the experimental group. Before surgery, X-ray and spiral CT were used to detect the data of abduction angle and the front rake of the healthy side of the patient, so as to perform THA as the reference value. In addition, Harris score was adopted to evaluate hip function 3 months after surgery in both groups. Also, the progression of Parkinson after operation was evaluated by Hoehn-Yahr grading method, and the complications were analyzed. Results: The results showed that the abduction angle measured by X-ray was 48.39 ± 4.15°, and the front rake was 13.83 ± 6.27°. In the experimental group, the abduction angle obtained by spiral CT measurement was 46.26 ± 3.92°, and the front rake was 12.44 ± 4.52°. The unequal length of limb was 1.10 ± 0.42 cm in the control group and 0.42 ± 0.21 cm in the experimental group. Moreover, the unequal length of limb in the two groups was significantly smaller than that before surgery (P < 0.01). The hip joint score of the two groups after surgery was apparently higher (P < 0.01), and the experimental group had significantly higher hip joint score (P < 0.05). Additionally, the experimental group had obviously higher Harris score of Parkinson's disease progression (P < 0.05). The occurrence rate of postoperative complications in the control group and the experimental group was 9.09% and 7.69%, respectively, which was not greatly different (P > 0.05). Conclusion: THA based on the data of spiral CT image measurement can achieve better postoperative results, which is conducive to recovering hip joint function and treating Parkinson's disease, and provides experimental basis for the diagnosis and treatment of Parkinson's disease in later clinical.
